I have an old built-in Baja spa that I estimate holds between 300-400 gallons. The original gas heat exchanger does not seem to be working and I am considering replacing it with one of the Hayward electric heaters. In the winter, the ambient air temp of the sunroom the spa is in is about 60-65 degrees, so I am guessing the water temp is around there when the pump is not running. What size (Kw) is recommended so I can raise the water temp to 104 degrees without waiting more than 2 or 3 hours? Tks Reply

I use Electric Spa Heater 11 KW - CSPAXI11
For jacuzzi pools with a water volume of ± 25m³. But the problem arises because the temperature in the water is only 35.4 ° C, what is the maximum temperature that should be reached with a volume of 25m³ of water? Reply

Hi, Yudha. The max temperature reached can vary depending on several factors like power, flow rate, surface area etc. The thermostat setting will also play a factor since it's analog. Reply

Hi, Vance. If the unit is leaking from inside, I'll recommend that you replace the entire unit. It will be wise to inspect the unit to find out where it is leaking from and to determine the cause of the leak so if you decide to replace it or possible repair it, it would not happen again. Reply

Good afternoon Brent, The tank is stainless steel so you would have to have it welded and pressure tested and there is no real guarantee that this will work. You can call Hayward and see if they have any recommendations @ 1-800-657-2287. I would recommend just replacing the unit. Reply

We have a 3,000 gallon salt water pool. I called Hayward and was told that a CSPAXi11 would be OK for our size pool. Double checking, (1) can we use/have installed a CSPAXi11 since we have a very small confined area for a heater, and we can only use electric. (2) what will we need besides a bypass and check valve when installing CSPAXi11. (3) does this heater come with double heating coils? and one real crazy question, (4) can we use two of these CAPAXi11 side by side for faster heating? Reply

Hi, The Hayward CSPAXI11 unit will be able to heater your pool. This unit will be fine if you have limited space and will require a dedicated 50 amp for each unit. You can install multiple units side by side for faster heating and this unit only has one heating coil. Reply

For a 50,000 gallon pool you will want a bigger unit. If you are wanting electric, a heat pump will be the way to go. I would recommend one that is at least 130k BTU's. So the RayPak 133k, the Hayward 140k, or the Pentair 140k heat pumps would be the ones you want to look at. Reply

This unit uses a straight 220v electrical connection. You will need to contact the manufacturer Hayward Pool Products at 908-355-7995 for the specific wiring questions you have asked. Reply

Will your heater work on an above ground pool 12'x42"?
Thank you Reply

After about 6 months of installation, the stainless steel container started to leak from the weld. I have two units like this, and the second one started leaking after 10 months. It says on the cover that the max pressure should be lower than 60 psi, my pressure was about 20 psi, so it looks like the manufacturing quality issue.

Great Spa heater

Pros: Easy to install

We have a home built 1,500 gallon "poolette" that we use as a splashing pool in the summer and in the winter we cover it and heat it for use as a spa. Previously we used a Vulcan 6kw heater from Grainger, but we had a pretty high failure rate. The Hayward heater brings the water temp up much faster and was very easy to install.

Whirlpool Heater

Reviewed By:Dr Bink

(6/11/2010)

Pros: Easy Installation

Cons: Element chamber developed leak around reset button

Package arrived in good condition with no defects. This system is used in a YMCA whirlpool setting, and the system is on 24/7. For the most part the system is reliable with the exception of the pressure switch, used in shutting system off if there is no water pressure. Because of the chlorination and chemicals we use for sanitation purposes, the unit tends to corrode from the inside out so longevity is only about 5-6 years. Unit is well put together and the price was better than our local Pools Plus, they wanted $759.00 for the same unit.
